I am changing the sprite image at runtime but its not changing.

[abhaya.agrawal]

When i am changing it on mouse click its changing and instantly going back to previous sprite.

this is the code i am using.

 public void Local()
    {
        localButtons.GetComponent<UISprite>().spriteName = "local_inner_shadow";
        cloudButtons.GetComponent<UISprite>().spriteName = "cloud";
    }

i also tried like this
public void Local()
    {
        UISprite sprite1 = localButtons.GetComponent<UISprite>();
        sprite1.spriteName = "local_inner_shadow";
        UISprite sprite2 = cloudButtons.GetComponent<UISprite>();
        sprite2.spriteName = "cloud";
    }

but same problem is there.

UIButton component will change the sprite. Do you have a button attached?

[abhaya.agrawal]

Yes button is attached.

So remove it.

As I said, button changes the sprite for you. If you want only color to change, use UIButtonColor instead.
